A Part-Time Accountant's Monthly GST Routine for BUSY Clients: Finish 2B Matching, Purchase Posting and 3B in One Day
पार्ट-टाइम अकाउंटेंट का मंथली GST प्लान: कई BUSY क्लाइंट, एक दिन में 2B मिलान, परचेज़ पोस्टिंग और 3B
A date-wise monthly GST plan for accountants who handle several BUSY clients: books, GSTR-1, GSTR-2B, IMS, purchase posting and GSTR-3B, and how to cut hours of purchase entry to minutes.
A part-time accountant in a town often keeps the books of five, ten or fifteen businesses, most of them on BUSY. Sales are usually entered by the client; the purchase bills, matching and returns come to the accountant in the last ten days of every month. That is where the evenings and Sundays go. A fixed routine, and letting a tool do the typing, gives that time back.
The month at a glance
| Date (monthly filer) | Work | Tip |
|---|---|---|
| 1st - 5th | Collect last month's purchase bills, bank statements, sales register from each client | One shared folder per client, same names every month |
| by 11th | File GSTR-1 (QRMP clients: IFF by 13th) | Match BUSY sales with the e-invoice / e-way bill data first |
| 14th | GSTR-2B ready; act in IMS on doubtful bills | Accept / reject before the 3B is filed |
| 14th - 18th | Book purchase bills in BUSY and match with 2B | This is the step that eats the most time |
| by 20th | File GSTR-3B (QRMP: 22nd / 24th) | ITC only as per 2B; liability as per GSTR-1 |
| last week | Supplier follow-up list, ageing, bank reconciliation | Send each client their missing-bill list |
Where the hours really go
- Typing purchase bills line by line: item, HSN, quantity, unit, rate and tax for every bill of every client.
- Matching with GSTR-2B in Excel, row by row, then correcting typing differences in BUSY.
- Finding bills the client forgot to send, which only show up in 2B.
- Re-work when a wrong unit or tax rate posts the wrong ITC and has to be corrected after the return.
A routine that fits in one day per client
Same checklist for every client
Use one checklist (our 20 checks before GSTR-1 and 3B) and tick it client by client.
Purchases from the portal, not from paper
For suppliers who issue e-invoices, the bill's full detail (item, HSN, qty, unit, rate) is already on the GST e-invoice portal. Fetch it instead of typing it; key in only the bills that are not e-invoiced.
Match before you post
Compare 2A / 2B with BUSY first, so only bills truly missing in BUSY are posted, and number / date / amount differences are corrected rather than duplicated.
Post with a pre-check
Check series, voucher type, dates and accounts before posting, then post in one go. Keep the import report for the client's file.
File and send
File the 3B from the matched figures and send the client a one-page summary with the missing-bill list.
What changes with Bharat GST Champ
Bharat GST Champ runs inside BUSY on each client's company. It takes the supplier e-invoices from the portal and posts them as BUSY purchase vouchers with the right BUSY item and unit, fills the remaining bills from GSTR-2B, and stops anything that could post wrong (unit not in the item, IGST + CGST mix, big gaps) with the reason. In our customers' work, about 3 hours of manual purchase posting in a month comes down to about 5 minutes of checking. The time you get back is time for one more client, or for your family.
Bharat GST Champ 3.0 does this inside BUSY. GSTR-2A / 2B / GSTR-1 compare with your BUSY vouchers, "Missing in BUSY" shown only when it is 100% safe to post, every mismatch kind in its own colour, and (Pro) supplier e-invoices posted straight into BUSY with item, HSN, qty and unit. Standard Rs 2,500 + GST, Pro with e-invoice import Rs 5,000 + GST per year; the free demo has all Pro features.
